Abstract:
A display device and an electronic apparatus comprising the same are disclosed. The display apparatus includes a photo-sensor for detecting ambient light and outputting a photocurrent according to the intensity of the ambient light, wherein the display apparatus comprises a current sampling unit and a light detection control unit. The current sampling unit is configured to sample the photocurrent outputted from the photo-sensor and to output a plurality of sampling signals to indicate the magnitude of the photocurrent. The light detection control unit is configured to determine an average of the sampling signals outputted from the current sampling unit. The current sampling unit starts a next sampling period corresponding to the end of one of the sampling signals.
Abstract:
PROBLEM TO BE SOLVED: To provide an intrusion detection device which reliably detects an intrusion into a specific area with a minimum delay.SOLUTION: An intrusion detection device comprises: a plurality of first optical marks 1a arranged along a border in a side of one area defined by the border; and a plurality of second optical marks 1b arranged so as to be paired with the plurality of first optical marks 1a in a one-to-one manner in a side of the other area defined by the border. At any time, when one of a pair is lit, the other of the pair fails to be lit. A part of control signals corresponding to a part of the plurality of first optical marks 1a is an error detection code of the other part of the control signals corresponding to the other part of the plurality of first optical marks 1a. The intrusion detection device detects an intrusion on the basis of a comparison result between a second portion of light receiving signals corresponding to a part of the plurality of first optical marks 1a and a first inspection value and a comparison result between an inverse bit string of a fourth portion of the light receiving signals corresponding to the other part of the plurality of second optical marks 1b paired with the part of the plurality of first optical marks 1a and a second inspection value.
Abstract:
A thermal absorption structure of a radiation thermal detector element may include an optically transitioning material configured such that optical conductivity of the thermal absorption structure is temperature sensitive and such that the detector element absorbs radiation less efficiently as its temperature increases, thus reducing its ultimate maximum temperature.
